Kernel panic - not syncing: Fatal exception in interrupt



LubOlimex

Hello there,

Please check the following topic: https://www.olimex.com/forum/index.php?topic=59.0

We have found that removing/unsoldering R17 (120R) increases stability. My suggestion is to apply this easy fix until we find a better solution.

Regards,
